ADDING AND RECORING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 605,705, dated June 14:, 1898.

Application filed August 11, 1897. Serial No. 647,890. (No model.)

To all whom, it may concern:

Be it known that 1, WILLIAM J. ENSWORTH, of Erie, in the county of Erie and State of Pennsylvania, have invented a new and Improved Adding and Recording Apparatus, of which the following is a full, clear, and exact description.

This invention is an apparatusfor registering and recording figures; and it comprises printing devices for impressing the numbers individually and registering-wheels for easting up the individual figures in a total or aggregate sum.

This specification is the disclosure of one I 5 form of my invention, While the claims define the actual scope of the conception.

Figure 1 is a vertical section of the invention. Fig. 2 is a detail section on the line 2 2 of Fig. 1. Fig. 3 is a detail section on the line 3 3 of Fig. 1, looking in the'direction of the arrow in said figure. Fig. 4 is a plan view of the invention. Fig. 5 is a fragmentary view illustrating the stop-plate. Fig. 6 is a fragmentary section showing in detail the keys for the printing device, and Fig. 7 is a fragmentary and enlarged perspective view showing the advancing pawls for the recorder.

The frame of the machine rests on a base 7 and has a main column 8. A standard 10 is mounted rigidly on the base 7 and carries a horizontal shaft 11, that passes through a bearing 12 in the upper portion of the column 8.

IIeld rigidly by the bearing 12 is a'horizontally-extending tube 13,Which loosely incloses three hollow shafts 1 1, 15, and 16. The innermost shaft 16 turns loosely on the shaft 11, and all of the shafts 14, 15, and 16 are 4 capable of revoluble movement independently of each other. The shafts gradually increase in length inward from the shaft 14, so that the ends of the hollow shafts are respectively extended one beyond the other.

Attached to the left-hand end of the shaft 11 is a bevel-gear 17, attached to the corresponding end of the hollow shaft 14: is abevel-gear 18, attached to the corresponding end of the shaft 15 is a bevel-gear 19, and attached to 5 the corresponding end of the shaft 16 is a bevel-gear 20. The bevel-gears gradually decrease in size inward from the gear 17. The gears 17, 18, 19, and 20 may move independently and horizontally with their respective shafts 1a, 15, 16, and 11. Running out rigidly from the column 8 is an arm 21, carryinglevers 22,which bear, respectively, against the gears 17, 18, 19, and 20 and by which the said gears, with their attached shafts, may be shifted horizontally. A ratchet-latch 23 is pivoted on the arm 21 and pressed by a spring 21. This latch holds the levers 22 in normal position. By moving the arm 23 against the spring 24 any desired one of the levers 22 may be operated to shift the gear with which it coacts.

The ends of the shafts 14:, 15, 16, and 11 opposite the ends having the gears 17, 18, 19, and 20 are provided, respectively, with wheels 25, 26, 27 and 28, which have wide peripheries with numbers thereon, each set of numbers running from O to 99. One edge of each periphery of the wheels 25, 26, 27, and 28 is serrated, and these edges are respectively engaged by spring-fingers 29, standing on the base 7 and serving to hold the wheels 25, 26, 27 and 28 in the positions to which said wheels may be put. Movement imparted to the wheels '17, 18, 19, and 20 will turn the shafts Whereonsaid wheels are carried, and the shafts in turn will impart movement to the wheels 25, 26, 27, and 28. These latter wheels are the registering-wheels, which show the total of the sums that are Written. Fig. 7, which shows the advancing-pawls for transmitting movement from one registering-wheel to the other, illustrates between each pair of the registering-wheels a bent arm 60, held rigidly by the arm 4E1. Fulcrumed 011 the arm 60 is a lever 61, arranged to be engaged by a pin 62, fixed on the contiguous registering-wheel. For each arm 60 the arm 11 carries a paWl 63, which pawls are respectively engaged With the levers 61. The pawls 63 respectively engage the toothed edges of the wheels 25, 26, and 27. lVhen a registeringwheel to the right of another registeringwheel turns a complete revolution,,the pin 62 on said turning-registering-wheel will rock the lever 61, which throws the coacting pawl :00

(33 and turns the contiguous rcgistering-wheel one point or notch. llythese means the reg ister is effected by a principle similar to the well known registering or adding devices. The parts 60, (53, t1, and (52 are so arranged that the necessary sliding of the registeringwheels maybe permitted withoutinterference by said parts. The shafts ll, 16, 15, and ll are pressed endwise in a leftward direction with reference to Fig. 1 by means of expansire spiral springs 30, bearing against the right-hand ends of the shafts 1-1, 15, and 16 and against the hubs of the wheels 35, 26, 27, and 28.

An arm 31, supported horizontally, has a bearing 32, in which a solid shaft 33 and three hollow shafts ill, 35, and 36 are revolubly mounted. Fixed to the shaft 33, at the lower end thereof, is a bcvebgcar 37, capable of meshing with the gear 20. Fixed to the lower end of the shaft 36 is a bevel-gearSS, capable of meshing with the gear 19.. Fixed to the lower end of the shaft 235 is a bevel-gear 30, capable of meshing with the gear 18, and fixed to the lower end of the shaft 2-34. is a bevelgcar ll), capable of meshing with the gear17. Rigidlysecured to the standard 10 is a fingerplatc ll, the lingers of which respectively carry hair-springs 42, attached to the shafts E36, 85, and 3t and to the hub of the wheel 37, such springs serving to hold the above-nained parts in normal position.

The upper ends of the shafts Bl, 35, 30, and 33 are arranged one above the other, the innermost shaft being the longest, and these shafts are respectively provided with horizontal recording-wheels which are of different diameters and which are arranged one above the other, the uppermost wheel being the smallest. l lach recoiding-wheel has a box 47 secured to its upper side and at the periphery thereof. Sliding vertically within each box at? is a spring-pressed key l8, on the lower end of which is a die ll). The dies 49 on each wheel bear numbers ranging from 0 to 90. The upper face of each key is printed with a number corresponding to the number on the die of said key. These keys, with their dies, serve as recording devices, and. each key moves through or across the plane of the wheel or wheels,below and between the spokes thereof, to effect an impression, as hereinafter described. Each wheel is of different diameter to permit the keys of one wheel to be struck without interfering with those of the other, the said wheels comprising each a hub 43 and a rim 4-5, connected by widely-separated and slender spokes :l:-l-, radiating from the hub, so that the keys will meet with. no impediment to their operation.

Carried in the upper end of the standard 10 and in an arm 50, carried by the arm 31, is a shaft 51, on which a roll 53 of paper is mounted, which roll may be handled in any desired manner. Arms 523 are respectively carried by the standard 10 and by the arm 50, said arms 53 carrying rolls of the inked ribbon The ribbon 5-]: runs transversely across the roll 59 of paper and beneath the rccordingu'heels.

The numbers are recorded by prcsr-ii ngd own the keys l8, so that the dies it!) may be engaged with the inking-ribbon 51- to impress the number on the roll 52 of paper. As will be more fully explained hereimifter, it may in some cases be desirable to protect from pressure certain elements of the numbers on certain keys. To attainv this end, I provide a plate 55, sliding in a bracket of), suitably supported on the frame of the machine, so that the plate will be located beneath tl 1c keys d8 of the recording-whcels. .lly moving this plate toward and from the ribbon 51L the plate may be made to cover certain figures of the numbers on the dies of the keys 18, so as to prevent the impression of said figures. riueh operation is illustrated in lig. 5.

The outermost wheel. of the recording wheels has its keys made to represent con is, and the die of each key on this wheel maybe provided with a decimal. point to sepz'irate the numbers struck by the keys of the said outermost wheel .from the ninnbcrs that are struck by the remaining recording-wheels, such latter numbers indicating dollars. lt will be understood that, if desired, the keys may be made to indicate numbers simply, with those of the said outermost rccru'dingwheel representing decimal. fractions. On the two recordlug-wheels next to the oldermost recording-wheel some of the keys and their corresponding dies have numbers with zero-marks before them. These keys on each wheel except the outermost recordlug-wheel. are the keys representing the numbers from 1 to 9. In some cases, however, it will not be desirable to strike these zero-marks for example, when the sum 202 is to be written. it therefore is the function of the plate to cover the zero-marks on the dies, so as to prevent the impression of said zeromarks on the roll 52; bu t should it be filth- 'cd to write the number 20,5202 the plate on is moved out, so as not to intml'ere with the impression of the 0 on the if key of the wheel which is in position to strike such ligu re.

llissuming now that it be desired to record and register acertain number, the recordingwheels are manually shifted so that the desired numbers will be arranged over the point at which the zcrouuarks of said. wheels are illustrated in Fig. it. The appropriate keys should now be depressed, whereupon the roll 52 will be impressed with the numbers on the dies. As the recordingavheels are shifted movement will. be transmitted to the gears ill, 39, I38, and 37 by means of the several. shafts on which said gears are carried. llrevious to this operation the levers should have been moved so as to mesh the gears 17, it 1.), and

20 with the gears 37, "*l, and ill. t onscquently as the latter gears are turned the gears 17, 18, 1.), and 2t) also willv be turned and the wheels 25, 2h, 27, and :36 will be moved.

so that the sum of the numberrecorded on IOC) llO

the roll 52 will be cast into the total shown by the registering-wheels 25, 26, 27, and 28, such total being read on said wheels with reference to any suitably-arranged indicatorpoint. hen the operation has been performed, the arm 23 should be moved against the spring 24, so as to release the levers 22 and permitthe return of said levers with their associated partsby the action of the expansive springs 30.
